Separate HAL driver registration with the threading (#7184)
* Separate HAL driver registration with the threading
Have synced drivers for {Dylib, VMVX}, and the global flags of
`IREE_HAL_DRIVER_{DYLIB, VMVX}_SYNC`, so the HAL driver registration can be
done with threadless configuration.
Enable iree/runtime libraries to be built in threadless configuration.
Clean up the usage of IREE_ENABLE_THREADING flag in iree/hal and iree/samples
Part of the cleanup for https://github.com/google/iree/issues/4298
* Make `dylib-sync` driver embedded library compatible only
This allows iree/runtime can really built in the bare-metal config
without the dynamic_library dependency, and the `-ldl` linker option.
This also removes the driver dependency in iree/samples/{dynamic_shapes,
variable_and_state} examples.diff --git a/CMakeLists.txt b/CMakeLists.txt
